About DetectGPT

DetectGPT is a free AI writing checker at detectgpt.io. The product is DetectGPT. The company behind it is CoreAI LLC. The job is a style score on finished prose: paste up to 3,000 words, or a public page URL, and see how much of the draft still sounds like a language model.

People land here because they cannot open a campus Turnitin® detector themselves, or because a client said “run it through Turnitin” when they meant any AI checker. DetectGPT is that self-check. No account. No school login. Independent, and not affiliated with Turnitin, LLC.

The homepage scores AI writing. The free plagiarism checker looks for public web overlap. Those are two different jobs. Neither one reprints a campus report.

We also run HumanizeAIText, a free rewriter for drafts that still sound generated. DetectGPT tells you where the prose is stiff. HumanizeAIText is the rewrite step. Same company. Different tools.

DetectGPT is not Turnitin®, ZeroGPT, GPTZero, or Originality.ai. A score here will not match theirs. Careful human writing can look even. Heavily edited model writing can look mixed. If a grade or a contract hangs on the result, keep your drafts and run more than one check.
